Math take two, Dino-Purse

Math take two, Dino-Purse

Back to the math, Continuing the Dino purse

This will be just a wee tiny post compared to my regular verbose discussions. I have been a bit run off my feet with fun layouts and drafts for various proposals for the upcoming 75th anniversary of the Ottawa Valley Weavers’ and Spinners’ Guild. I am also involved with the monthly summer library days and the guild got a gift of 10 sheep and 2 alpaca fleeces, my car is still a bit aromatic. Since I am sure more changes on layouts are awaiting in my email, I better tell you about the continuation of the Dino bag quickly and then get back to work.

When we last chatted about the Stegosaurus, I had just been dealt a crushing blow by numbers, evil uncaring numbers who thwart my want of a phone-carrying device!!!

From my misinterpretation of Ann’s suggestion, I had wound up with a much bigger carrying device than originally intended.  What do you mean you did not mean 50% added to each side?

1) scaling up, a bit over enthusiastically small paper stegosaurus lying over a stegosaurus twice as big drawn on a resist.1) scaling up, a bit over-enthusiastically

A quick review:

I had created the shape I wanted and then added gussets for the top and bottom. (This is how you can make a sewing pattern. But unlike sewing patterns felt patterns need a lot more “seem allowance” for shrinkage.  Figuring how much was where I derailed.)

After a bit of Consoling from Ann (it was such a cute dinosaur and I had been so careful in the measuring and redrawing!) Ann reviewed the math (ick) half of the distance, then half that again and put the halved half on each side. Ok, I think I can’t screw that up twice (don’t tempt fate but really I think I got it this time. <mutter mutter stupid dyscalculia>)

Next, we considered how to add the gussets to the side section.

2) Adding the belly gusset to the body shape. Ann pointing at paper pattern pieces of body and belly gusset2) Adding the belly gusset to the body shape

Ann suggested lifting up the legs (to be added separately, which I had considered as an option as well) and then drawing in half the belly gusset.

3) talking about adding the back gusset Ann pointing at space between plates.3) talking about adding the back gusset

Again take off the plates and add half of the back gusset.

The plate can be made separately. Which will allow them to be heavily/ stiffly felted. If I then leave a fuzzy end, I can attach them to the body partway through felting.

4) side panel of Stegosaurus with legs and plates folded up, ready to be traced to make a new template. ready to trace onto another piece of paper.4) side panel of Stegosaurus with legs and plates folded up, ready to be traced to make a new template.

Now to create the new pattern.

5) drawing half the width of the belly and back gussets to the side pattern this makes a large slug like shape5) drawing half the width of the belly and back gussets onto the side pattern

I traced the stegosaurs then added the half belly and back gussets to the body shape. I marked where the legs and plate went for reference. I have now achieved Stego-Blob!!

Ok, let’s try again on expanding the pattern:

When I weave, I usually measure my warp length with a string with knots marking the loom waste and the halfway point in it. When I made tamari balls, I used a folded paper band with pins. I am going to avoid the ruler I used last time with those untrustworthy misleading numbers and resort to a reliable piece of paper I can fold in half and then half the half.

6)Drew a grid over the new shape and found a scrap paper to use as a measuring tool. there is a mettle yardstick various pattern pices and a role of painters tape.6) Drew a grid over the new shape and found a scrap paper to use as a measuring tool.

I did use the ruler to make the graphed lines but carefully ignored most of the numbers.

graph overlay on blobby shape letters indicate horizontal lines bisecting shape and numbers indicate vertical lines bisecting shape.7) graph overlayed on the blobby shape made by adding the belly and back gussets to the body.

On each vertical line, I took my scrap paper and matched the distance from one side of the stego-blob to the other along the line. I folded that distance in half on the paper then folded it in half again. That distance was then added to the top and bottom of the line and a point was plotted.

As I got closer to the head and tail you can see (in picture #6) that the increase is greatly lessened. By the time I had all the vertical lines plotted,  Ann was looking a bit concerned by the curvature around the nose and tail.

I explained this was only step one in the expansion plan. Step two would be to plot the horizontal lines next. Then as step 3 would be to average the two plotted dots and figure out the new outline. Ann said she would just estimate and go from there.

Oh no, time to stop!! A tornado warning just went off on my phone. No wind outside but that may literally be the calm before the storm.  When we chat again, I will let you know how the horizontal lines go and then average the points to make the new MEGA-Stego-Blog!!  (only 6 pages in Word, It is a tiny blog today.)

Update: looks like there was a tornado in Barhaven, it’s a suburb in the southwest end of Ottawa and North of Ann, it’s located between us. There is another band of the storm system coming later this afternoon but most of it should be south of both Ann and me, just in case it is more aggressive than it looks on the weather map I better get this posted!!! yep, the tornado alert just went off again but there is sunshine coming in my office window, so I will keep working on this rather than hide in the basement, but I will keep an eye on what’s happening out the window, just in case the weather changes its mind. (There is lots of comfy soft wool to keep me safe in the basement, but just not the specific wool I need for projects I am working on!!)

  1. It must be frightening to shelter in the basement waiting to see if the tornado hits or not.

    Our sympathies go to you as you struggle with the math on the dinosaur template – it’s far more complicated than it looks at first.
    We’re really looking forward to seeing how Dino progresses – have you chosen colours yet?

    1. We were very lucky, it hit about 10-15 minits south of was the lead story on the national new last night (with Montrial which got hit by the same storm, but more flooding there). thankfuly tornados are not too frequent but we have had a few the last few years (who ever is enjoying our normal winter probubly traded us there horrabile winds?)

      i have discalula, i know im not the only one so it may be handy for anyone with similer thots on math to see how i thwort the evils of math. realy i did much better at math in the higher grades, i liked algabra, i dont remember how to do trig, or geomatry but passed the classes at the time. i wish i had taken statistics i have enjoyed data analisis and i am shure it whould have been usefull. but what is this number divisable by, or what is the sum of two unlike fractions… or getting a colloum of number to add up to the same answer more than onece is frustrating. or even just reading out a long string of numbers can get totaly messed up (lets not think about useing fone numbers that my phone dosnt know already).

      it is amazing what you can acomplish with a pice of string or a bit of folding paper. using a grid in the way that i am is not as fast as Ann’s fabulous mathimatical skills and on the fly estimating but we should both reach the same concultion, i just have a slightly longer journy to enjoy. (sort of like you who read quickly dont get to enjoy the book for as long as i do!)

      i am still thinking about colour, i know it will not be pink… i am thinking maybe browns and green tones with the flushed redish tone for the plates which were said to be highly vascularized. when i was in Kindergarden (before grade 1) there was a paliantaligist who had a hypothisis that the blood vesels in stegosaursus plates may be a cooling system, which would be unnessisary in a cold booded creature. i was watching the university level paliantology course saterday morings on TV at was fasinating, ocationaly they ran one of the math or english courses at that time slot, a great disapointment, not fun.

      i will definatly show you the shape i wind up with and see if i can attach the legs, plates and spines. i hope you avoid the ill weather and it gets lost by the time it hits the ocian and cant find the UK!

  2. Wow Jan, complicated (to me) & time consuming. Congrats on your perseverance and coming up with a way that perfectly suits you, to create your reduced Mega-stego-bloba-saurus. Looking forward to seeing the next instalment.

    Keep us posted about the tornado – that you are all safe and damage free. It sounds like you are very familiar with the routine, you are obviously made of sterner stuff…. I’m not sure how we Brits would cope if we had to add tornadoes into the mix too 🤪

    1. Thanks!! it may take me a bit longer to get there but i will get it all maped out!

      my first tonado was in grade school, it came down the ottawa valley moving west to east along the river, it took a turn jsut noth of us and ransacked the escarpment on the Quebec side of the river (near where Bernadette now is). the previous one to this went on the other side of the road from the post office that my hubby works at. that one was on the ground much longer and brot frends with it. it hit about 5 minits south of us and bounced and draged its way across a cuple nabour hoods. there is a distictive sky colour, and the sound of a close one is somewhere between a ill behaved train and a ground flying turbo airplaine. last years mico birst was much sneekyer, the sky was ominous then suddelny it was similer to a bunch of anoyed toddlers having tempertanturms. i hate this tree but not that one, oh smote the bus with a tree, rip up a fence, twist up the plants in a line in my garden but lift before hitting the house ( it did take a cuple big branches from the nabours tree) that storm had a massive path with spots of distruction then nothing then another temper tantrum. we again were very lucky! storms have been geting much more intence (i still suspect the weather knows when i put out wool to dry and it dosnt like us!)
      if you dont have tornados… how many of us can come visit? i could trade you some of our snow, though its not as impresive in amounts as it use to be.)

  3. Ah, yes, tornado season is upon us. Head for the basement, grab some water, and… back to felting. That phone case has a life of it’s own Jan! But it’s going to be amazing when you’ve brought it under control. Really looking forward to seeing the final results.

    1. Thanks!! at least this one didnt take a sudden turn towords you! the one that hit Dunroben (west of Ottawa) bounced across the river and ravaged the escarpment on the Quebec side.
      i am vary glad i have a basement! and that is full of wool, looms and spinning wheels! maybe a bit too full.
      i worry my stegosaurs may develoup a personality as the Mers have. maybe if i felt faster there will be less ?

  4. Hats off to you Jan, I wouldn’t know where to even start with this one!!! Can’t wait to see the result. I’m sure you’ll get there though.

    As for the tornado, I empathise. I live in the UK, but the two occasions I’ve visited my son in Amarillo, Texas, I’ve found myself in midst of a tornado scare. Thankfully, like you, they blew past a couple of miles from me! But last time, having been at his in-laws where they have an underground shelter, after it had passed we tried to get back to his apartment and got caught in the flash flooding. Every street we turned down, there were police road blocks, abandoned vehicles, crashed cars etc. It was like something out of a movie!!!

  5. I hope the tornados have passed you by and you are able to continue with your doing as least as possible math calculations. The string or paper method works great. I have been using that a lot with book folding. Less measuring, figuring involved all around. The dinosaur is coming along and I look forward to seeing it completed. I’m sure it can be friends with the Mer family and you could start a show (kind of like the Flintstones) 😉

  6. It is neat to see your process Jan. I look forward to continuing to follow along as you work this out.

  7. I’ve finally found time to sit down and read the post Jan. Looking at the little smile on the face of the Stego in your original pattern, I think he’s enjoying himself. I think he’s definitely up for a meeting with the Mers, and I can imagine the mischief they’ll get up to together.
    Thank heavens you have so far (touch wood, fingers crossed) not been hit by a Tornado. Long may that continue.
    You are very busy at the moment, but I’m looking forward to the next instalment, when you’re able to fit it in.

  8. The steggoblob is coming along. He/she(?) will be amazing. I think I may steal your template and with a few changes make ? not sure I like the spiky tale but I’m not sure I want all the plates. Either way it would be mostly purple, of course. LOL
    The tornado was a 30 min from me. We keep an eye on the sky and listen. The sky tend to go greenish and it gets very still and quiet first. My basement, although good for lambs is not that wonderful for people to sit around in. We do seem to be having more of them. I think of them more in the USA mid west, tornado alley.

    1. Glad the tornado missed you – long may it continue.
      I’m beginning to think that, what with heat waves, droughts, earth quakes, volcano eruptions and big storms as well as antibiotic immune viruses, that the planet is fighting back! The trouble is, even if we do manage to limit global warming, what we have now is probably the new norm. Depressing or what? All the more reason to lose ourselves in our arts and crafts to keep the “black dog” at bay.

  9. Goodness, I hope the tornado didn’t make an appearance later! I can’t imagine having to watch out (listen out?) for your phone for these alerts and having to run somewhere to wait for the storm to pass… I really shouldn’t complain about the comparatively mild Scottish wind 🙂

    Your dino is going to come out great, I’m sure of it! Can’t wait to see it finished. Does it have a name already?

We'd love to hear your thoughts!
